Topic: Replace connected 3dPolylines end to end as one LWpoly

[Coder]

Hello,

I have a few groups of 3Dpolylines connected to each others ( end to end ) and I would like to convert each connected objects to LWpoly as one.

I don't know how to iterate through the selection set and group each connected 3dpolys to replace them with one LWpoly at the end so I hope someone could help me with this urgent routine.

Thank you in advance.

Unless all of your 3D polylines are coplanar, you will not be able to convert them to an LWPolyline object, which is a planar object.

Here is an old program of mine for joining 3D Polylines, but the result will be a 3D Polyline:

Thank you for your kind reply.

Correct but I need to get the two end points then create the LWpoly regardless of the Z coordinates.

Sorry I did not notice your edit of your replay.

Great, your program helps a lot and that 3Dpoly also works with me. 

Thank you Lee so much.
